Original application filed January 25, 1911, Serial No. 604,621.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Divided and this application filed September 25, 1915. Serial No. 52,664.

Y '0 all "whom it may concern Be it known that I, JOSEPH L. HILLER, a citizen of the United States, residing at Mattapoisett, in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Bearings, of which the following is a specification.

This invention relates to improvements in bearings, is a division of application, Serial No. 604,621, filed January 25, 1911, and has particular reference to the interal construction of the bearing.

It is an object of this invention to provide a hearing which is capable of doing heavy work at high speed; for use under unfavorable working conditions where careless attendance prevails; which is provided with a continuous liner extending from end to end of the bearing to present a relatively large supporting surface for the shaft; to provide a support for the liner throughout substantially its entire length; which has an oil reservoir or chamber extending continuously throughout the length of the bearing; and which is provided with means for sealing the bearing to exclude the entrance of dirt and to thus prolong the life of the parts of the bearing and the journal or shaft supported therein.

Other objects and advantages of this invention will be brought out more in detail in the following disclosure of one specific embodiment of the invention, the same being.

disclosed in the accompanying drawings wherein Figure 1 is a side elevation of the bearing and its support. Fig. 2 is a longitudinal vertical section of the same showing a shaft in place in the bearing. Fig. 3 is a transverse section of the bearing taken centrally on the line 3-3 of Fig. 2. Fig. 4 is a transverse section taken on the line H of Fig. 2. Fig. 5 is a transverse section on the line 4L1 of Fig. 2 showing the liner in position to be removed, and Fig. 6 is a top plan view of the lower portion of the bearing.

The body of the bearing comprises the two main sections or halves 11 and 12 which are supported in any convenient manner, as, for instance, between the sup ort or pillow block 18 and the bearing cap 1 7 The body of the bearing is of considerably greater length than the width of the support and cap. In the present disclosure, the sections 11 and 12 of the body of the bearing are provided with ball or spherical surfaces 13 and 14: about their middle, adapted to bear on corresponding surfaces 15 and 16 provided respectively in the bearing cap 17 and the pillow block 18. By this construction, the body of the hearing has universal support. The section 12 of the bearing is provided with transverse ribs 19 while the section 11 is provided with registering transverse ribs 20 which are cast integral with the members 11 and 12, respectively. The ribs 20 of the upper half of the hearing are babbitted for contact with the shaft, while the lower ribs 19 are machined for supporting a liner 21 thereon which engages beneath the shaft. The liner 21 is suitably babbitted for providing a bearing surface for the shaft. The liner 21 extends substantially throughout the entire length of the bearing, the same terminating but a short distance from the extremities of the bearing to provide spaces 22 and 23 which extend down into thebottom of the bearing and are adapted to receive solid oil rings during the positioning or removal of the liner as hereinafter pointed out. It will be noted that the ribs 19 are secured at their ends to the sides of the lower section 12 and that they provide therebeneath an uninterrupted oil reservoir or chamber extending in a straight line from end to end of the hearing and opening at its ends respectively into the spaces 22 and 23. The oil rings are of suflicient diameter to dip into the middle of the reservoir and carry the oil up over the shaft.

The two sections or halves 11 and 12 of the bearing are secured together by bolts 25 and are provided within their abutting edges or faces with oil grooves 26 extending 1ongitudinally of the bearing and opening through the inner wall thereof. The oil grooves are adapted to catch and return oil seeping through the crevices between the adjoining edges of the upper and lower sections of the bearing.

The opposite ends of the bearing are sealed or closed to prevent access of dirt to the interior of the bearing and to prevent leakage of oil from the hearing. The outer end of the bearing is closed by a plate 27 secured to the end of the body by screws 28 and holding a packing ring 29 against the end of the bearing to form a tight joint. The opposite or inner end of the bearing is provided with an internal flange 30 formed well within the end of the bearing and having its outer face finished to form a square shoulder to receivethercagainst a collar 31 on the shaft, the projecting end of the hearing being bored to make a reasonably close fitwiththe circular periphery of the collar 31and-provided about the collar with a .grooveBQ to whiclngrease islsupplied from a grease cup 33 opening into channel Behto form a seat. The inner end of the bearing also provides for a thrust, bearing,the rease between the contacting surfaces of the shoulder30 andthe collarBl not only lubrieating these partsbutalso providing an effective sealagainst the entry of any foreign matter whatsoever into the bearing.

It-willloe noted that when it is desired to inspeetthe bearing the top half'll may be -rea dily removed by simply removing the top cap17 ofthe support. The liner 21 may be :removed without disturbing the lower half of thebcaring, orwithout removing the shaft by applying a spaliner-wrench to the holes in the endsofthe liner, and rotating the liner until it assumesthe position shown in Fig. ,5 atthe top of the bailing. lVhen the liner is'in this position, the rings lt-yvirtue of thechamfered edges of the liner and the lower half of the hearing may be easily raised and moved longitudinally of the shaft-to the end spaces 22 andQ-s of the bearing and font of'contact with the liner. Z'l-he,linermaynow belifted from the shaft.

As shown in '2 of the drawings, the oil reservoir or chamber extends the full length of therbearing and is open throughout its length;being-unobstructed by any ribs or other projections. The bottoinof the reseryoirrtapers downwardly toward the middle of ;the bearing where it is lowest, and a drainage passageway 36 is provided which extends froma central depression 37 down through thesupport 18. An opening in the support 18 is made for this passageway and the latter is normally closed in any suitable manner A free and unobstructed circulationofalarge body of oil isthus assured in the ari The lower half 12 of the bearing is of larger radius than the upper half 11,-and a-s V the liner is one piece and extends throughout the entire length of thebearing, the liner is ,held from rotation from its bottommost position by engagement of its upper edges with the lower edges of the ribs 20 of the .upper section 11 ofthe'bearing. It will also be noted that the body of the hearing as a whole is held from rotation in the socket formed 'by the support 18 and cap 17, by the engagement of theedgesii'? of the lower half 12 .of the bearing projecting laterally beyond the edges of the upper half 11 and into engagement with the lower faces of the cap 17. '1 will be noted that the top surface Q the s tio 12 Qfthe he ring is -tical' plane,

sloped in opposite directions from a central of the bearing and the cap 17 of the support,

-a11d there is thus no interference when oscillation of the bearing takes place in a ver- I claim:
